Pittsburgh Police launched an internal review in coordination with the city's citizen review board to determine whether officers used proper force during a confrontation with an angry fan at a Pirates game on Saturday, reports the Pittsburgh Post-Gazette.

Officers used their TASERs and batons to subdue Scott James Ashley, a 41-year-old Friendship resident.

In a clip posted to YouTube of the arrest, Detective Francis Rende and Officer Jeffrey LaBella are seen striking Ashley several times before taking him to the ground and handcuffing him. The officers had attempted to TASER Ashley, who then assumed a fighting stance.

Fans had been yelling "USA!" as the fan refused to comply with officers, as a reference to his red, white and blue jacket, reports CBS News.

The apparently incident began when Ashley yelled an expletive at an usher, who then threw him out. A second woman was arrested, when she confronted officers following Ashley's arrest, reports WPXI.
